Introduction of Computer Programming, Problem solving techniques, algorithm specification and development, Programming style, debugging and testing, documentation. Program design methodologies, structured and modular program design. Programming Language in C: Introduction to C, programming file structure: purpose of .h and .c files, Simple Makefile, constant, variable and data types, operator and expression, type conversion, decision making, branching and looping, arrays and strings, user defined functions, structures and union, bit field and bit-wise operations, pointer, file management in C, command line arguments, dynamic memory allocation and linked list, preprocessor, low level programming, managing input/output operation. Unix Shell: shell command, filters, viewing file and statistics, comparing and sorting, pipe, text processing, regular expression, grep family, stream edit with sed. Shell Programming: variables, environment variables, built in variables, defining words – quotes; test – string, number, file properties, Bolean operators; control structure – if-then-else, case, while loop, for loop. Make: Managing large program, Makefile, Makefile rules. Awk Programming: command line syntax, input, output, pattern matching, expressions, control statements, built in variables, arrays, built in functions, user define function

About the Course
Hardware vs. SoftwareSystem Software vs. Application SoftwareOperating SystemWhat is language? Programming language?Syntax vs. Semantics?What should we expect after completion this
course?
Learning Style
This course is practical oriented.We will give lots of assignments.
(because practice makes a man perfect )
Memorization will not help you to get a good result.
Copying Code: Strictly prohibited. Will be severely punished if you are caught.
Typing Speed (Not related to this course but Important)
Important for every student in CSETry to type in grammatical way
Use 10 fingers to type
Use software to learn grammatical way of typingSpeed:
Should be at least 30 WPM (Words per minute) Preferable 35+ WPM.
Rewards..Software
Ten Thumbs Typing Software, Or, any other Typing tutor software, I will provide you two of them.

Description of C
General-purpose languageProcedural (= functions + data)Mid-levelRelatively small, simple to learnCross-platform language, single-platform compilers
(unlike Java)Char-based
17
Why C?
Prior to C, two broad types of languages: Applications languages
High-level COBOL, etc. Portable but inefficient
Systems languages Low-level Assembly Efficient but not portable
Goal of C: efficient and portableHow: abstract above hardware arch, but not far!
18
Why not Java, C++, etc.?
Java is safe and elegant, but slowC++ is unsafe and fast, but highly complexC is unsafe, but succinct and fastC/C++ is still used for:
Systems programming Windows, Unix, etc.
High-perf back-end servers
A Simple C Code
#include <stdio.h>
int main()
{
printf(“Welcome to CSE105\n”);
return 0;
}
How to Run
Save a source code with extension “c” or “cpp”. (Ex: first.c)
Compile it and link it Output: first.exe
Run the program.Output of the program:
